About SolViewer
SolViewer is a free suite of developer and SEO tools, operated by the SolViewer product team, for inspecting public webpage responses — from raw HTML source to headers, on-page checks and social previews.
No accounts or paywalls. The tools report only the public response and page-level signals they can retrieve.
Open SolViewerInspecting a web page should take seconds, not minutes. Most developer and SEO tools are buried behind logins, credit limits or bloated interfaces that get in the way of a simple question: what is this page actually doing?
SolViewer was built to answer that question instantly. Paste a URL or drop in some HTML and get back formatted source code, HTTP headers, an SEO audit, social preview cards, robots directives and more — all in one place, all for free. Our editorial standards and methodology explain how the same team writes, reviews and updates supporting guidance.
We believe the best tools feel invisible. SolViewer gets out of the way and lets you focus on the page you're working on.
Each tool focuses on a defined part of a public page response, with its limits made clear in the result and supporting documentation.
Every tool works without creating an account. We don't want barriers between you and the information you need.
SolViewer tools are free to use. We don't impose credit limits or rate caps on basic usage.
Results should appear in seconds. Every tool is optimized to minimize waiting and maximize usefulness.
We surface what's actually on the page — not what you want to hear. Good tools tell the truth.
Debug HTML structure, check response headers, validate robots rules and spot broken markup without leaving the browser.
Audit on-page signals, inspect meta tags, check canonical URLs and preview how a page appears in search and social feeds.
Verify that Open Graph images and descriptions look correct before sharing a page on social media.
Run quick audits on client sites, compare page structures and produce reports without subscribing to expensive platforms.
URL tools send a public HTTP or HTTPS address to SolViewer’s fetch service. The service accepts only those two schemes, rejects URLs that carry usernames or passwords, and refuses localhost, .local, .internal, and private-network addresses before it opens a connection.
Each request waits at most 12 seconds, follows at most five redirects, and reads at most 2 MiB of the response (a sitemap request may read up to 50 MiB; a child sitemap or robots.txt request stays at 2 MiB). The fetch does not run page JavaScript, so markup injected only after the document loads is absent from the result. Discovery probes used by the SEO Checker look for /robots.txt, /sitemap.xml, /llms.txt, /llms-full.txt, and /favicon.ico on the same origin; those probes are samples, not a site crawl.
Pasted HTML, pasted robots.txt, pasted headings, and the HTML Viewer stay in your browser. They are not sent to the fetch service.
